VMware Performance and Capacity Management - Second Edition

Storage

Let's recap what we need to produce in order to monitor storage capacity:

• A line chart showing the maximum and average storage latency experienced by any VM in the datastore cluster
• A line chart showing the datastore disk capacity left in the datastore cluster

The first line chart tracks performance, while the second one tracks utilization.

Storage – performance

Just like compute, we just need to add the average super metric. The actual formula is as follows:

avg(${adaptertype=VMWARE, objecttype=VirtualMachine, attribute=virtualDisk|totalLatency, depth=2})

Storage – utilization

Storage disk capacity should be tied with your actual, physical capacity. If you are using thin provisioning at the storage layer, then you need to measure it at this level. ...
